ADJUSTABLE GUARD FOR WATER-GAGE `GLASSES.

SPECIFICATION forming part of Letters Patent N o. 769,452, dated September 6, 1904.

Application filed April 30, 1904. Serial No. 205,690.

To (all 'Ich/mt 'it 'nt/ty concern:

Be it known that l, (urnoRGn il'. Anus, of Brainerd, Crow lVing county, Minnesota, have invented certain new and useful lmprovements in Adjustable Guards for lVater-(irage (lasses, oi' which the following isa specification.

M y invention relates to a water-gage g'lass vt'or steam-boilers; and the object otthe invention is to provide a device consisting' ot` a shield or g'uard to protect the engineer and lireman from injury by steam and flying' glass resulting `from the breaking ot' the waterglass.

A further object is to provide a g'uard that is adapted for use on Water-glasses of different length and also upon lubricating-glasses.

The invention consists g'encrally in providing' an adjustable guard that can be readily adapted for water-gage glasses ot' dil'ferent length.

Further, the invention consists in various constructions and combinations, all as hereinat'ter described, and particularly pointed out in the claims.

In the accompanying' drawings, forming part ot this specitication, Figure l is a vertical section ot' a water-gage glass and guard embodying' my invention. Fig'. Z is a vertical section on the line if a' of Fig. l looking' toward the back of the guard. Fig. 3 is a horizontal section on the line 1/ z/ oi' Fig'. l. Fig. l is a similar view on the line of Fig. 1 looking' toward the under side ot' the guard. Fig'. 5 is a section on the line w' fw of Fig'. 1. Figs. 6, T, and 8 are details showing' the means for adjusting the device to adapt it to water-glasses of ditierent length. Fig'. 9 is a sectional view through a portion otl one ot' the heads.

Vln the drawings, 2 and 3 are the g'age-cocks at the top and bottom, respectively, of the water-glass i and connected therewith by the usual coupling' 5, having' gaskets 6, that form a close joint with the wall of the tube. The

guard is provided with heads 7 and 10, having dovetailed slots 1l and 11, wherein corresponding'ly-shaped plates 1Q and 12 are titted. These plates are readily removable to permit (No model.)

the convenient placing' ot' the guard in its position around the water-glass, and the Vlower plate has dowel-pins 13', titting within re cesses 13'/ in the edges ot' the slot. l prefer to bevel the edges oi' the slots and provide corresponding' edg'es on the plates, as shown in Fig'. 9, and when the couplings have been inserted into the heads and the lock-nuts 9 tightened, one being' turned up and the other down, the guard will be held firmly in place and the water-g'lass drawn to its proper position between the gage-cocks. By removing' the plates from the slotted heads the guard can be attached or detached from the coupling's without removing the water-glass.

The head T is provided on three sides with slots l2 to receive the glass panels 13, that inclose the water-glass on three sides, said panels being' of sutltieient thickness to withstand the strain resulting' from the sudden breakag'e ot' the water-glass. The lower ends ot' these panels tit within grooves la in the head 10 and are locked therein by means ot' brackets l5, that are adjustably secured to the head 'T by means ot' screws 1G, that lit within slots 17in said brackets. By loosening' these screws the brackets can be raised or lowered for the purpose oi' adjusting' them to the length of the panels. This construction allows the guard to be adjusted to adapt it to the variation in the thickness and number of the gaskets used in connection with the gage-cock couplings. Upon loosening' the screws 16 the brackets or clips can be readily adjusted or removed to allow access to the panels. The corners of the ends or heads 7 and 10 on the Vfront side are provided with annular recesses 18 to receive anglo-bars or corner-plates 19, that lap over the abutting' corners of the glass panels and hold them in place and at the same time present a neat finished appearance to the front of the guard. Clips 20 are provided on the under side o'tl the head l0 to support the cor- Y ner-plates.

On the back side of the device the heads are connected by a metallic plate 21, having a series of holes Q2, produced by pressing' or punching' out tongues 23 from said plate. These tongues are arranged at an incline, as

shown, and serve to direct the water and steam and broken glass down upon theenginedeck.

The device shown in Figs. l and 2 can be adapted to lit water-glasses of different length by setting up the device, marking the panels and plates, then removing them, and cutting them ofi' to the desired length.

In Figs. 6 and 7 I have shown a modification in the construction of the corner bars or plates which consists in providing a plate 24,

iitting in the head of the guard in the usual' manner and telescoping with a corner-plate 25, that is mounted in the lower head and provided with a longitudinal slot 26, wherein a thumb-screw 27, carried by the plate 24, is slidable. By'loosening this screw and adjusting the corner-plates the heads of the guard can be moved toward or from each other to adapt the device for water-glasses of different length. The heads and corner-plates of the guardcan be stamped out of sheet metal suitably finished, and the panels are preferably7 made out of heavy plate-glass, except the one at the rear, which is of metal.

This device is adapted for use on steamboilers of all types, but isparticularly designed for locomotive-boilers, where the position of the engineer and fireman in the cab exposes them to personal injury in case of breakage of the glass. rlhe device is also adapted for use with lubricating-glasses after being cut a suitable length for the purpose.

The slots 12 are beveled on one side to permit the glass panels to be conveniently inserted from beneath in case the gage-cock should be in the way above the head-plate. rI`he device is adapted for use on any length of water-gage glass by assembling the parts and marking' and cutting off the panels and back and corner plates to the desired length. If the construction shown in the modification is employed, it will only be necessary to cut ofi' and mark the panels, the angle or corner plates telescoping to correspond to the length of the water-glass.

I claim as my invention# 1. The combination, with Athe water-gage cocks and their couplings, of a water-gage supported between said couplings, heads or end plates mounted on said couplings and closing the top and bottom of the guard against the passage of glass and water, glass panels connecting said heads, and a metallic panel connecting said heads at the rear of said guard and having a series of perforations arranged to direct the water and broken glass down upon the engine-deck.

2. In a guard for water-.gage glasses, the combination,with ahead or end plate, of panels removably mounted therein, and brackets mounted on said head and adjustable toward or from the end of said panels, for the purpose specified.

3. A guard for water-gage glasses, comprising heads or ends, glass panels connecting said heads, a metallic panel connecting said heads and having a series of depending tongues formed by pressing or punching' out slots or holes therein, for the purpose specified.

4:. A guard for water-gage glasses comprising heads or ends adjustable toward or from each other and closing the top and bottom of the guard against the passage of water and glass, a panel connecting said heads and adjustable in one of them to allow said heads to bemoved toward or from each other to adapt the guard foruse on water-glasses of different length.

5. A guard for water-glasses, comprising head or end plates, panels connecting the said plates, telescoping angle-plates connecting said head-plates at the intersection of said panels, said telescoping plates having a slotand-thumb-screw connection, for the purpose specified.

6. A guard for water-glasses, comprising two heads, and panels connecting the same, corner or angle platesprovided at the intersection of said panels, each corner-plate comprising two sectionsattached respectively to said heads and having a sliding connection with each other.

7. The combination, with the water-gage cocks and their couplings, of a water-glass connecting said couplings, end plates fitting on said couplings and held between the lock-nuts thereof and said cocks, one plate being above and the other below its locking-nut and closing the top and bottom of the guard against the passage of water and glass, and panels connecting said heads.

8. A guard for a water-gage glass, comprising heads having slots to receive the gagecouplings, a plate removably' fitting said slots, and a series of glass panels connecting saidv heads.

9. A guard for a water-gage glass comprising two heads secured to the gage-cocks and having dovetailed slots, correspondinglyshaped plates removably fitting in said slots, and panels connecting said heads.

10. The combination, with the water-gage cocks and their couplings, of a water-glass connecting said couplings, end plates fitting on said couplings and held between the lock-nuts thereof and said cocks, one plate being above and the other below its locking-nut and closing the top and bottom of the guard against the passage of water and glass, corner-plates connecting said heads and being adjustable to permit the use of said guard on glasses of different length, and glass panels connecting said heads between said corner-plates.

In witness whereof I have hereunto set my hand this 16th day of April, 1904. l GEORGE W. AMES.
